DARPA has succeeded in creating hollow-core photonic-bandgap optic fiber, which allows light to travel along its length at around 99.7% the speed of light, or a 30% improvement over conventional ...

Now the world is a step closer to that reality, as researchers at Toshiba have demonstrated quantum communications sent over a record-breaking 600 km (373 miles) of optical fiber.

Now, researchers have developed an ytterbium-doped optical fiber at room temperature. By avoiding the need for expensive cooling solutions, the proposed method offers a cost-effective platform for ...

Optical fiber was used to both control and measure qubits, with promising results: the new set-up resulted in accurate rendering of the qubit's state 98% of the time, which is the same accuracy as ...

A new type of optical fiber filled with nothing but thin air has been found to be particularly effective for carrying out quantum key distribution (QKD), a security protocol that is in principle ...
